The symbols are so large that the category scatter chart can easliy display a solid bar of color. If I can make the symbols smaller or semi transparent it would helpful. Any help?
I'm not sure this helps any but if I were using that chart and couldn't show distinction between the values, I'd try to extend the scale of the chart first and see if that spreads them out (doubtful). Next I would see if I could display that data more effectively using another chart type. I don't know what data you're looking at or what you're trying to show, but think about another way you can present the message you're trying to tell. Maybe a Bubble Chart, then you'd be able to use series in there to show different colors and sizes. Maybe just simplify your message and use a Horizontal chart without doing anything too fancy. Sorry if that doesn't help, but hopefully it does. - matt
